DOOR-STOP.

Specification of Letters Patent. Patented Apr. 11, 1916.

Application led November 27, 1915. Serial No. 63,776.

To all whom z't may concern:

Be it known that I, THOMAS J. LYNCH, a citizen of the United States,residing at lVaterbury, in the county of New Haven and State ofConnecticut, have invented new and useful Improvements in Doorvb'tops,of which the following is a specification.

This invention is an improved door stop or door check, adapted to engagewith the floor and either prevent a door from being opened, or to limitthe extent to which the door may be opened, the object of the inventionbeing to provide an improved device of this character which may bereadily attached to a door, and the floor engaging member of which isnormally in inoperative position but may be released and caused toengage the floor and thereby prevent the door from being opened, orlimit the extent to which the door may be opened when desired.

The invention consists in the construction, combination, and arrangementof devices,

hereinafter fully described and claimed.

In the accompanying drawings z-Figure 1 is an elevation, partly insection of ay door stop constructed in accordance with my inventionshowing the same attached to a door and with the floor engaging memberin engaged position in full lines and arranged in inoperative positionin dotted lines. Fig. 2 is a horizontal sectional view of the same.

For the purposes of this specification, a portion of a door is indicatedat 1 and a floor at 2. In accordance with my invention, I provide aframe or casing 3 which may be made of sheet metal or other suitablematerial and comprises a back wall 4 and a pair of parallel verticalwalls 5.

The floor engaging member 6 is a pawl pivotally mounted as at 7 betweenthe walls 5 of the frame or casing and near the lower outer cornersthereof. -A spring 7a is arranged in the frame or casing with its lowerend secured as at 8 to the back wall thereof, near the bottom. Thisspring may be of the form here shown or of any other suitable form. Thespringbears against the inner side of the floor engaging member 6 whenthe latter is in raised inoperative position, and when said floorengaging member is released, the spring serves to turn the floorengaging member outwardly so that by gravity, it drops to and engagesthe floor and hence serves to secure the door against being opened or ifthe .oor is already partly opened, serves to prevent the door from beingopened to a greater extent. I alsoprovide a detent 9 to hold the pawl orfloor engaging member normally in inoperative position. The said detentis pivotally mounted as at 10 in the upper portion of the frame orcasing at a point near the inner upper corners of the walls 5 and has adepending outer arm 11 to bear on the outer side of the member 6, theweight of the detent serving to cause it to normally hold the member 6in raised inoperative position. At the lower end of the arm 11 is anoutturned lip 12 which may be readily engaged by the foot so that thedetent may be quickly lifted and thus cause the member 6 to be releasedand thrown outwardly by the spring and engage with the floor to stop orcheck the door.

By the usek of my invention, an intruder may be prevented from enteringthrough a partially opened door and the door may be securely held inclosed position or against movement inwardly when in partly openedposition.

Having described the invention, what is claimed is:

1. A door stop comprising a frame having a back wall for attachment to adoor and a pair of side walls, a floor-engaging member pivotallymounted` between the side walls, at a point near the lower ends of saidside walls, and a detent pivotally mounted and arranged to bear on theupper ends of the side walls and having a depending outer arm to bear onthe outer edges of the side walls and to engage and hold the upper endof the floor-engaging member, when the latter is in raised inoperativeposition, said detent coacting with the casing to form a housing for thefloor-engaging member.

2. A door stop comprising a frame having a back wall for attachment to adoor and a pair of side walls, a floor-engaging member pivotally mountedbetween the side walls, at a point near the lower ends of said sidewalls, and a detent pivotally mounted and arranged to bear on the upperends of the side walls and having a depending outer arm to bear on theouter edges of the side walls and to engage and hold the upper end ofthe floor-engaging member, when the latter is in raised inoperativeposition, said detent coacting with the casing to form In testimonywhereof afiX my Signature m presence of two Witnesses.

THOMAS J LYNCH.

a housngfor the fiom-engaging member, and a spring to turn theHoor-engaging member outwardly from the casing when the detent is raisedand to press the floor engaging member outwardly against the dependingarm of the detent, when the floor engaging member is in raised position.
